Plastics ***The word plastic comes from the Greek word plastikos, meaning "able to be molded." ***Thermoplastic is a material that is plastic or deformable, melts to a liquid state when heated. It can be melted and reformed numerous times. ***Thermosetting plastics (thermosets) are polymer materials that cure, through the addition of energy, to a stronger form. The curing process transforms the resin into a plastic or rubber by a cross-linking process. A thermoset plastic cannot be melted and reformed.

Resin Identification Numbers
* In April 2000 we received an from a site visitor: "I was picking up pop and beer bottles along the highways of southeast Indiana in 1968 and the bottles had a 2¢ deposit on them before that." Another source gives the date of the first "bottle law" was enacted in Oregon in 1972.

Did you know???? The energy saved by recycling one soda bottle will:
Power a 100 watt light bulb for almost an hour Power a computer for 25 minutes Power a color TV for 20 minutes Power a washing machine for 10 minutes

Plastic Facts Over 6.5 billion pounds of plastic were produced in 2006
Over 16 million tons of plastic waste is generated annually in the U.S. and about 2.2% of all plastics is currently recycled. It takes about 450 years just for one plastic bottle to break down in the ground!

Interesting Recycling Facts
The United States makes enough plastic film each year to shrink-wrap the state of Texas. If you lined up all the polystyrene foam cups made in just one day, they would circle the earth. Plastic bags and other plastic garbage thrown into the ocean kills as many as 1,000,000 sea creatures every year ! Americans use 4 million plastic bottles every hour! -- Yet only 1 bottle out of 4 is recycled
11
Interesting Recycling Facts
About 1,200 soft drink and salad dressing containers could carpet the average living room. Each year American throw away 25 billion Styrofoam cups, enough every year to circle the earth 436 times. In 1988 we used 2 billion pounds of HDPE just to make bottles for household products. That’s about the weight of 90,000 Honda Civics.

Disposable Diaper Recycling
The Knowaste Process 1. The process begins with shredding the incoming materials which breaks apart the diapers. Once the incoming materials are shredded, they are sent to a pulper. 2. The pulping action opens up the diapers. This begins the process of separating the components and exposes them for chemical treatment. Sanitizing occurs at the pulper. The plastic is removed by finger conveyors and is sent to trommels. 3. The plastics are processed in trommels, where residual fibers and waste are removed by washing. Then the plastics are then pressed and pelletized for sale to the market.
20
4. The pulp stream goes to coarse screening to further remove plastics which are also sent to the trommel. This stream is chemically treated to deactivate the SAP to make it possible to separate it from the fiber. 5. The deactivated SAP, along with residual small plastics, is separated from the fiber through a cleaning process. The deactivated SAP can be collected and reactivated for reuse. 6. The fibers are then put through a fine mechanical washing, cleaning and screening process. This produces a clean, marketable fiber. The reject material is sent to a sludge press.
21
7. The clean fiber is then pressed, baled and sold into the market
7. The clean fiber is then pressed, baled and sold into the market. These fibers are of excellent quality as they contain very high quantity of Softwood Kraft. 8. The water extracted in the washing and thickening steps is sent to internal treatment using a dissolved air clarifier and recycled in the system as dilution water. 9. The sludge from the clarifier, as well as the fine screening and cleaning rejects, are thickened and sent to composting, for which they are well-suited and break down readily.
